Title: Navigationsverfahren in einem kraftfahrzeug
Inventor: ENGELSBERG ANDREAS
IPC: G02B27/00
Filed: 2001-07-28
Abstract: Es wird ein Navigationsverfahren in einem Kraftfahrzeug vorgeschlagen, das dazu dient, einen Pfeil als Richtungshinweis auf einer Windschutzscheibe in Abhängigkeit von Signalen von einer Blickrichtungserkennung darzustellen, wobei die Richtungsinformation von einem Navigationsgerät festgelegt wird. Bei Annäherung an eine zu wählende Abzweigung wandert der Pfeil in Richtung der Abzweigung. Weiterhin verkürzt und/oder wechselt der Pfeil seine Farbe und/oder eine Blinkfrequenz. Auch eine Drehung des Pfeils in Abhängigkeit von der angegebenen Route auf der Windschutzscheibe ist möglich. Die Projektionseinrichtung mit der das Navigationsgerät verbunden ist, weist Mittel auf, um den Pfeil im Blickfeld des Fahrers zu plazieren.

Title: Sicherheitsdruckflüssigkeit und -verfahren mit nanopartikeln
Inventor: HAUBOLD STEPHAN
IPC: C09D11/30
Filed: 2002-12-16
Abstract: Die Erfindung betrifft ein beim Druckvorgang durch ein oder mehrere enge Düsen Druckflüssigkeit ausspritzendes Druckver­fahren bzw. eine für ein solches Verfahren geeignete Druckflüssigkeit. Die Erfindung bezieht sich insbesondere auf den Aspekt der Fälschungssicherheit eines Drucks auf Papieren oder Gegenständen. Gekennzeichnet ist das Druckverfahren bzw. die Druckflüssigkeit dadurch, dass die Druckflüssigkeit zur Fluoreszenz oder Phosphoreszenz anregbare Nanopartikel enthält. Diese Nanopartikel sind kleine kristalline Teilchen, die entweder selbst oder mit Dotanden versetzt zur Fluoreszenz oder Phosphoreszenz anregbar sind. Einzelne Punkte (10, 12) können mit Nanopartikel enthaltender Druckflüssigkeit gedruckt werden. Wegen ihrer geringen Größe von 1 bis 1000 Nanometern, vorzugsweise im Bereich von 300 Nanometern Durchmesser oder auch sehr viel kleiner - je nach Düsendurchmesser, besteht nicht die Gefahr des Verstopfens von sehr engen Tintenstrahldüsen. Die Anregungs- und Fluoreszenzemissionsfrequenzbereiche sind schmalbandig, so dass für eine Sicherheitskontrolle des Drucks die entsprechende wellenlängenspezifische Anregung bzw. Detektion erforderlich ist. Dadurch wird die Fälschungssicherheit erhöht.

Title: Urea prodn from ammonia and carbon dioxide
Inventor: SCAGLIONE PLACIDO
IPC: C07C273/04
Filed: 1968-12-13
Abstract: Reaction between NH3 and CO2 is carried out at 200-300 atm. and 160-230 deg.C and the effluent gas mixture consisting of aqs. urea, ammonium carbamate and NH3 in excess, is brought into contact with a gaseous mixture of hydrogen, nitrogen, and up to 14% CO2 at the same perssure. The ammonium carbamate decomposes and the products of decomposition, CO2 and NH3 are liberated and dissolved up in water along with the excess NH3 from the reactor. This soln. is then led back to the reactor and the whole process is carried out at the reactor pressure. The decomposition of the ammonium carbamate and liberation of the gases and subsequent absorption in water may be carried out in several steps if required. Improvement in the return of unreacted starting materials into the system leads to overall efficiency and less decomposition of product.

Title: Heat pipes with modified working fluids for - use at low temperatures
Inventor: GAMMEL GREGOR
IPC: F28D15/04
Filed: 1969-04-30
Abstract: Heat pipes are closed systems in which a fluid is evaporated in one section where heat is absorbed and recondensed in another section, where it is given up again. Water, because of its high latent heat of evaporation, can be used to produce heat pipes with high heat conductance but its use is limited at low temperatures by freezing. This can be overcome by the use of antifreeze additives such as alcohol, fluorocarbons, inorganic salts or silicone oils. The principle is claimed for all working fluids. The devices find application in space travel, cryogenics and for semiconductor elements.

Title: Switching system for signal sources connection - has a switch allocated to each signal source and a signal level controller
Inventor: FRANKE FRITZ
IPC: H03F3/72
Filed: 1973-11-07
Abstract: The signal sources are connected to an amplifier input, with signal levels maintained about constant in spite of different levels delivered by the signal sources.

The normally blocked input transistors are made conducting by application of a base voltage. The input transistor emitter is connected to a tapping of a voltage divider between the voltage source and frame. Its one resistor is the emitter resistor. Its base is connected to the tapping of another voltage divider between a D.C. voltage and frame. It is connected to its voltage source when the corresponding signal source is operating. The input transistor is conducting only when this second voltage divider is connected to its D.C. voltage source.

Title: Pressurised fluid supply system for motor vehicle - has central pump and valve kept open by given pressure level
Inventor: LEIBER HEINZ
IPC: B60T17/22
Filed: 1973-12-03
Abstract: The pressurised fluid is supplied by an automatically regulated pump with a small storage container to a number of elements and the circuit ensures that the brake system is preferentially supplied. The system uses a solenoid valve with a pressure sensor for opening the valve when a specified pressure is exceeded. The valve opening depends also on the presence of sufficient quantity of fluid. The pump is driven by an eccentric on the generator shaft. Pumped fluid is stored in the container having a pressure sensor. The comparator detects pressure loss and energises the valve for cutting off all circuits except the brake circuit. When the engine is at standstill the pump can be actuated by a battery.

Title: Transferring indicia onto glass or polished surfaces - by applying a film onto a carrier printing the indicia on the film, pressing the film onto the glass base and removing the carrier
Inventor: MESSERSCHMITT ELMAR DR
IPC: B44C1/17
Filed: 1973-12-11
Abstract: Indicia are transferred onto glass or polished surfaces by printing or applying, on a carrier having a surface which will promote separation, a soft and elastic film which is not inherently adhesive and has a thickness of 40-95 mu; pressing the film firmly onto the glass or polished surface e.g. with the aid of a doctor blade; and then stripping off the carrier. The film with the indicia will adhere firmly to the glass base without recourse to adhesive, thus avoiding the need of cleaning the glass once the indicia are no longer required and it is desired to remove them. The carrier may be siliconised glassine paper (imitation parchment). The film may be made of highly plasticised plastisol e.g. PVC which is subsequently gelled. The printed indicia may be produced e.g. by screen printing.
